Abstract
⺠This study investigates the surfactant effect and segregation effect from InAs surface quantum dots (SQDs) by incorporating antimony (Sb) into the QD layers. ⺠The Sb surfactant effect can extend planar growth and suppress dot formation. ⺠Photoluminescence reveals an enhancement in the optical properties of InAs SQDs as the Sb BEPs increase. ⺠Transmission electron microscopy images demonstrate that Sb segregates close to the surface of the SQD.
